The 0 particularly described. cross-shaft 26 has the bevel-gear 28. The In the drawings the dye-vat is shown at bevel-gear 1% of the camshaft 7 engages with 13 and is of the usual or any approved conthe bevel-gear 21 of the shaft 12, and the struction.

At the 5 5 side lengthwise of the machine are top rails ends of the reciprocating bars 4, adjacent to or bars 9, fastened to the tops of said standthe cross-shaft 26, they are also provided ards 1, as seen in Fig. 1, and constituting a with flanged ways 29 30, and on the crossiixed frame. From the top rails 9 the vertishaft 26 two circular disks 31 31 are eccencal bars 15 fastened thereto extend downtrically mounted similar to the eccentric cir- 10c ward into the vat 13, and on each side lengthcular cams 5 5; but there are no cams on said wise of the machine bottom rails or bars 16 shaft 26 like the cams 6 on the shaft 7.

The yarn skeins are shown at 32, passing around the yarn-sticks 2 3 and 10.

Having thus described the several parts of my device, I will now explain its operation.

The vat 13 is partially filled with the dye liquor. The yarn is hung in skeins upon the yarn-sticks, as illustrated in Fig. 1., the lower half or other proper portion of the skeins being submerged in the dye liquor and absorbing the same. Power applied by the belt 22 turns the pulley 21 and with it the shaft 7 and its cams 5 5 6 G. IVe will suppose that all the parts of the device are in the relative positions shown in Fig. 1. It is there seen that the yarn-sticks 2 3 lie side by side and that the reciprocating bars are in their lowest position, nearly in the plane of the top surface of the top rails 9. The rotation of the shaft 7 turns the cross-shaft 26 by reason of the bevel-gearing ll 2i 25 28, and as these bevel-gears have the same number of cogs the circular eccentric-cams 5 5 and 31 31 move at the same time and with the same speed. The action of said cams 5 5 31 31 is to periodically and regularly lift and lower the bars 4 l and their connected yarn-sticks 2 2. The cams 6 (5 on the shaft '7 turn with the cams 5 5 and are fast on said shaft and may be either fast on the cams 5 5 or made integral therewith. The cams G G abut the edge of the cross-pieces 19, as shown in Figs. 3 and l, and the rotation of the shaft 7 and said cams (5 6, bearing forcibly against the edges of said cross-pieces 19, cause the bars 4: 4 to move longitudinally to such a distance as is determined by the longest radius of the cam 6. The combined action of the lifting-cams 5 5 and the reciprocating cams G (5 is to cause each yarn-stick 2 first to rise from the position shown in Fig. 1 to the position shown in Fig. 3, at which point the radius of the cams 6 6 begins to increase, and the bars a a are then moved longitudinally to the position shown in Fig. a, where it is seen that the yarnsticks 2 and 3 are in vertical planes considerably apart. The return or reverse motion of the bars at l is caused by the weight of said bars and of the yarn with which they are loaded on said yarn-sticks 2 and also by the frictional drag of the cams 5 5 01 31 upon the ways 18 29, which thus automatically carry back the parts from the position shown in Fig. at to the position shown in Fig. The movement of each of the yarn-sticks 2 caused by the combined action of said cams 5 5 6 6 and said spring, is indicated by the dotted curves K K in Fig. 3. The effect of this movement of the yarn-sticks 2 2 upon each of the yarn skeins 32 is as follows: The skein is first lifted ofi the fixed yarn-stick 3 (see Fig. 3) and the top of the skein is moved a distance equal to that of the longest radius of the cams (3 6, so moving the whole skein bodily without any rotation of the yarn-sticks, as heretofore has always been necessary. It will be observed that by this bodilylifting of the skein from the yarn-sticks 3 by the yarn-sticks 2,

(illustrated in Fig. 3,) followed by the bodily lowering of said skeins, as described, dispenses with the frictional drag of the yarn upon the yarn-sticks, as heretofore, and so prevents any wear or waste of the yarn from this cause during the dyeing operation. The lowering of the yarn-sticks 2 brings down the yarn skeins so that they rest upon the tops of the yarn-sticks 2 3, as before. the yarn skeins are gradually and regularly moved upon the sticks and are immersed and drawn through the dye liquor in such a manner as to secure uniformity of color and to prevent all entan glin g of the skeins with each other, thereby avoiding the breakage and damage which have heretofore been experienced in the dyeing of yarn.

I claim as a novel and useful invention and desire to secure by Letters Patent- 1.
